ELECTRIC SIGNAL FOR HAY-PRESSES.

To all whom it may concern Be it known that I, CHARLES SGHADE, a citizen of the United States, residing at Cropsey, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Electric Signals for Hay-Presses, of which the following is a specification.

This invention relates to electric signaling devices for hay presses and an object of the invention is to provide an electric signaling circuit part of which is closed by the metallic frame of the ordinary dividing block as the latter moves through the press.

Another object of the invention is to pro vide improved rolling contacts adapted to dig into the hay or straw being packed and engage the metallic frame of the ordinary dividing block for completing an electric signaling circuit.

A still further and more general object is to provide a signal audible at the plunger end of the press which shall sound after a predetermined amount of hay has been passed, thereby insuring the making of uni form bales.

WVith these and other objects which will appear as the description proceeds the in vention resides in the combination and arrangement of parts more fully described and claimed hereinafter.

In the drawings, where a single embodiment of the invention is shown, and wherein similar reference characters designate corresponding parts, Figure 1 is a perspective view of part of a press showing a dividing block completing the circuit, Fig. 2 is a side elevation of part of a press showing the invention in signaling position, Fig. 3 is an enlarged fragmentary plan view showing a form of contact associated with the invention, and Fig. 4 is a vertical section taken through the upper part of the press looking toward the signaling apparatus.

In the use of ordinary hay presses the size of the bales depends upon the skill of the operator in estimating the amount of hay to be bundled.

To assist the operator to form more uni form bales my invention provides a bell or audible signal and suitable current supply which are part in circuit with the metallic frame of the hay press dividing block when a predetermined amount of hay has been put in the press. A spring is insulated from but operatively connected to each of a pair of Specification of Letters Patent.

levers connected in the signal circuit and carrying rolling contacts adapted to engage the dividing block.

The following more detailed description will give a better understanding of the invention.

As shown in Figs. 1 and 2 the press to which my invention is applied is of the ordinary construction having ways or guides 1 and 2 between which slides the dividing block 3 having the metal reinforcing strip or frame 1 all of which is old. Mounted upon the upper guide or way 1, is a block 5 extending entirely across the top of the press and having the ends thereof approximately in alinement with the sides of the top of the press. Each end of the block 5 has secured thereto a bracket 6 the lower end 7 of which is turned outwardly and eyed. The top of each bracket 6 is turned inwardly as at 8 and secured to the block by bolts 9 which pass through a fulcrum member 10 the outer end of which is also eyed, the eyes being practically in alinement. Passing vertically through these eyes is a lever rod or rocking arm 11 held against. downward movement by pins 12 or other suitable means and having the upper end bent to form a lever arm 13 to the outer end of which is pivoted a link 1%. The inwardly extending ends of the links 141- are provided with insulators 15 which receive the hooked ends of the helical spring 16 used to draw the arms 13 together normally. The lower end of each arm 11 is bent substantially parallel to the arm 13 as at 17 and has secured thereto a fork 18 in the end of which is mounted a horizontally disposed spile sprocket wheel 20 the extended teeth of which are adapted to engage the strip 4 on the dividing block as the latter passes, the block swinging the sprocket wheel outwardly about the lever rod 11 as a center and against the tension of spring 16. Mounted upon the block 5 is a housing 21 within which is located a battery 22 a pole of which is connected to a bell 28 by conductor 24. The bell is also connected by a conductor 25 to one of the arms 13 or one side of the block while a conductor 26 connects the arm 13 upon the opposite end of the block to the other pole of the battery.

The operation is obviously as follows: Hay is passed through the press as usual and the dividing block inserted. The dividing block passes to the position shown in Fig. 2 with the unbaled hay to the right thereof and as soon as the metallic frame 4T engages the spile sprocket wheels 20 it will. move the same outwardly against the tension of spring 16 as previously described, whereupon current will flow through the following circuit (see Fig. 4;) battery 22, conductor 2 1, bell 23, conductor 25, one of the arms 13 to the corresponding spile sprocket wheel 20, the metallic frame or strip 4 of the dividing block, through the remaining sprocket wheel 20 and corresponding arm 13, conductor 26 back to the battery. The insulation members 15 prevent short circuit of the current through the spring 16.

I have shown a battery as adapted to ring a bell both of which are located upon the press but evidently other sources of current may be used and other forms of signals not necessarily audible may be used.

My invention is equally applicable to paper presses, cotton presses, etc. The rotating of the spile sprocket by its projections engaging the hay insures a rubbing contact between the ends of the projections and the metallic frame of the dividing block. It will also be apparent that the entire signaling equipment is carried by the block 5 so that the same may be removed and re placed without altering any other part of the press.

What I claim is 1.. A signal for hay presses using dividing blocks provided with metallic frames comprising a pair of arms pivotally mounted one upon each side of the press, resilient means insulated from and interposed between said arms adapted to draw the same together, roller contacts connected to and moving with the arms, and an electric circuit containing the roller contacts adapted to be closed as the contacts engage the metallic frame of the dividing blocks.

2. A signal for hay presses using dividing blocks provided with metallic frames comprising a pair of vertical lever rods pivotally mounted one upon each side of the press, a pair of substantially parallel arms extending from each lever rod, resilient means insulated from and interposed between corresponding arms on the lever rods adapted to draw said arms together, roller contacts carried by the remaining arms held normally in the path of the advancing dividing block, and an electric signal circuit having said rollers for terminals adapted to be closed as the dividing block engages said rollers.

In testimony whereof I afiix my signature in presence of two witnesses.
